Gadget interesting essential?

The table on this board on the internet is very well done and accessible from iOS (iPhone) and Android (tablet).
The pedometer is clipped onto a lot of things (pants, belt buckle) and not moving.

No problems with the product. Think about the value of this product, as for me, I bought a little on a whim. I'm very happy (use of a sportsman who wants to follow in the medium and long term), but it is actually especially for sedentary people wanting to lose weight (weight monitoring and very well made food taking into account various measurements and fat levels).
